How does a netbook connect to the internet?
Netbooks can connect to the internet via a 3G wireless network, a Wi-Fi network, or in some cases, via a wired Ethernet cable. 3G-enabled netbooks have a built-in cellular radio and so do not require a separate wireless internet card. When accessing the internet from home, hotels or coffee shops, Wi-Fi can be a cost-effective supplement to your 3G wireless plan, since Wi-Fi access normally allows unlimited data use for free or a fixed fee. To switch from the 3G network to Wi-Fi, you simply flip a switch on the netbook. Some netbooks also have a built-in Ethernet jack, thus enabling internet access when Wi-Fi and 3G wireless networks are not available.
